There were a lot of fun things about #IBMTechXchange 2025 last week, but one of my favorites was our "Doom Takeover" at the Monday evening expo hall party. Instead of running our demos, I just had people logging into an IBM #LinuxONE #mainframe and playing Freedoom over VNC #Doom 😁
Working on documentation for a whole matrix of support (client vs. server OSes), stay tuned!

I'm running a virtual tutorial at IBM TechXchange Dev Day on June 25th!
It'll cover some basics of logging into the #IBM #LinuxONE Community Cloud and using Linux, and conclude with an overview of some of the open source AI/ML tooling available.
Session is at 1PM Eastern / 10AM Pacific and it's called: "Linux Fundamentals, Topped with a Touch of AI" 🍨🐧

My hand-picked team that ran the IBM #LinuxONE AI Arcade at the #RedHatSummit knocked it out of the park. Thank you JJ and Alex!
I had so many great conversations this week, and I had a wonderful time making new friends and catching up with old ones.

Kick off day in the #RedHat Summit expo hall is behind us!
Lots of great conversations, people had fun with the games 🕹️
Want to take part in the CLI game fun at home?
Start with a VM from the IBM #LinuxONE Community Cloud: https://community.ibm.com/zsystems/l1cc/
Then follow our arcade instructions on GitHub: https://github.com/linuxone-community-cloud/arcade

I am looking at running things like #ERPLibre + local AI models on this. Sovereign, encrypted workloads in your country. Makes sense ?
"Today, IBM announced the launch of their latest server: the new #IBM LinuxONE Emperor 5. This fifth generation redefines IBM’s LinuxONE system as their most secure and high-performing Linux computing platform for data, applications and trusted AI.
#Canonical supports #LinuxONE Emperor 5 with #Ubuntu Server. "

Today the #IBM #LinuxONE 5 was announced 🎉
I share some pictures, including a couple directly from the test floor from @psqlctln !
I'll be honest, I dig into AI a bit. But listen, the new AI accelerator is really cool, and the clients we work with use them for some real, beefy, inferencing work (like real-time fraud detection for that credit card you tap). No trendy AI here, just serious stuff IBM Research has been working on for years.
